Oh What a Lovely War is a theatrical chronicle of the First World War, told through the songs and documents of the period. First performed by Joan Littlewood's Theatre Workshop at the Theatre Royal, Stratford East, London in 1963, it received the acclaim of London audiences and critics. It won the Grand Prix of the Theatre des Nations festival in Paris that year and has gone on to become a classic of the modern theatre. In 1969 a film version was made which became a popular success in its own right.
